Hi
I prepared my own yolov3-tiny for use in raspberry pi 4 and NCS2.
and try to convert custom yolov3-tiny model to IR
this is my step
1. I try this command " python convert_weights_pb.py --class_names obj.names --data_format NHWC --weights_file train.weights --tiny " I got the file " frozen_darknet_yolov3_model.pb "
2. from my test.cfg file
[yolo]
mask = 3,4,5
anchors = 10,14, 23,27, 37,58, 81,82, 135,169, 344,319
classes=1
num=6
jitter=.3
ignore_thresh = .7
truth_thresh = 1
random=1
[route]
layers = -4
[convolutional]
batch_normalize=1
filters=128
size=1
stride=1
pad=1
activation=leaky
[upsample]
stride=2
[route]
layers = -1, 8
[convolutional]
batch_normalize=1
filters=256
size=3
stride=1
pad=1
activation=leaky
[convolutional]
size=1
stride=1
pad=1
filters=18
activation=linear
[yolo]
mask = 0,1,2
anchors = 10,14, 23,27, 37,58, 81,82, 135,169, 344,319
classes=1
num=6
jitter=.3
ignore_thresh = .7
truth_thresh = 1
random=1
so I edited yolo_v3_tiny.json and rename to yolo_v3_tiny_mymodel.json
[
{
"id": "TFYOLOV3",
"match_kind": "general",
"custom_attributes": {
"classes": 1,
"anchors": [10, 14, 23, 27, 37, 58, 81, 82, 135, 169, 344, 319],
"coords": 4,
"num": 6,
"masks": [[3, 4, 5], [0, 1, 2]],
"entry_points": ["detector/yolo-v3-tiny/Reshape", "detector/yolo-v3-tiny/Reshape_4"]
}
}
]
3. I try next command " python mo_tf.py --input_model frozen_darknet_yolov3_model.pb --input_shape [1,416,416,3] --data_type FP16 --tensorflow_use_custom_operations_config yolo_v3_tiny_mymodel.json "
I got this error
(TF114CV41) D:\ML\tensorflow-yolo-v3-master>python mo_tf.py --input_model frozen_darknet_yolov3_model.pb --input_shape [1,416,416,3] --data_type FP16 --tensorflow_use_custom_operations_config yolo_v3_tiny_mymodel.json

Hi teeradet,
Thanks for reaching out. Could you please try converting your model using the latest version of OpenVINO™ toolkit (2020.4)?
Let us know if the issue persists.
Regards,
David C
